FREDERICK GILES, OF SOUTH YARRA, NEAR MELBOURNE, VICTORIA.

ELEVATOR.

SPECIFICATION forming part of Letters Patents No. 483,145, dated September 27, 1892.

Application filed November 18, 1891. Serial No. 412.309. (No model.)

To all whom it may concern:

Be t known that I, FREDERICK GILES, a citi- V zen of Melbourne, in the Colony of Victoria,

Australia, and asubject of the Queen of Great Britain, and a resident of 15 Fawkner Street, South Yarra, near Melbourne, Victoria, have nvented a certain new and useful Improved Apparatus for Retaining Lift Cars or Cages at any Point of their Travel, (and that no patent has been granted me in any country for this invention,) of which the following is a specification.

The object of this invention is to stop lifts, and especially passenger-cars, at any point of their travel, and is particularly for use in stopping them firrnly and securely at the floor and for the time during which the passenger is alighting from or enter-ing into the car. The means at present in use-namely, the closing ot the lift-cylinder valve by pulling the rope actuating the sameare found insuffi cient, as when the conductor by said rope stops i the car the latter jerks either Upward or downfrightened, and consequently the ntlity of ward, with the result that nervous or other persons unacquainted with lift traveling are lifts is considerablyreduced. Where this invention is in use, the conductor in stopping the car by the valve-rope before referred to simultaneously (by turning the handle conveniently placed in the rear of the car) operates mechanism, which results in the ends of transverse bars proceeding into the guides or skids along which the car works, and the latter is thus made immovable during pleasure, so that the passenger can alight without the disagreeable and dangerous jerks which at present are caused by the means in use. Es-

pecially will this invention be found of great value and utilityin cases where the conductor is either inexperienced or inattentive, as in the former case considerable practice is required to be gained to know the exact point at which to pull the valve-rope, so as to bring the floor of the car and landng level with each other.

The invention comprises a vertical rod, which is provided with a handle conveniently placed at and suitably affixed to the back of the car, and so out of the way of the passengers. To this rod is attached by means of disk are attached by pins or otherwise two transverse rods, which work in guides bolted to the floor of the car, said rods being provided with springs. The ends of these bars when actuated proceed into and remain while desired in the guides orskids against which the car works. 011 these transverse bars shoulders are formed, between which and the guides aforesaid the springs exert their force foraocelerating the result caused by the car-conductor turning the handle and putting the apparatus in action. i

Reference may now be had to the accompanying drawings, in which- Figure l is an elevation of the apparatus as erected in a passenger lift-car, the door of the latter being removed for clearness sake. Fig. 2 is a plan of same, the car-floor being removed for a similar reason. In this figure the open and locked positions of the mechanism are shown by dotted lines. Fig. 3 is an elevation illustrating the vertical rod and le- Vers.

In the figures, A is the vertical rod, provided at its upper end with the handle A' and suitably mounted in hearing-guide A bolted to the back A of the car. To this rod A are attaehed guide-brackets B, in which the locking-rod B' works, provided with a thumb or hand piece B and spiral spring 13 which operates between one of the aforesaid guides B and a shoulder 13 formed on the rod B'. The end of the latter rod B' looks into a base-plate 13 which also serves as lower hearing for the vertical rod A. Thisplate 13 is fastened to the floor of the car and, if preferred, can be made fiush with same. The rod A proceeds downward through the floor of the car, and at its lower end is attached to a lever C. This lever at its other end is forned with a joint ICO or bifurcation C', in which the end of a con necting-rod D is held by pin D'. The other end of this rod D is affiXed to the under side of a disk E, said disk being attached to the floor of the car in such nanner that it rotates the desired distance. To this disk E at its upper side are held the transverse bars F by pins F' or otherwise and made of a bent forn, as shown. These bars work in guides F bolted to the car-floor, and are provided with spiral springs 1. which work between the guides F and shoulders F formed on the bars. The ends F of thelatter when actuated proceed into the holes or other formations in the skids G. H is the car, J being the shaft of the building in which it travels.

The 'modus opera ndz' of this inven tion is as follows: Assune a passenger is in a lift-car and desires to alight at the third floor of the building, the conductor upon being notified pnlls the valve-rope herein referred to and so stops the car. He also grips the handle A', sinultaneously pressing the thunb-piece B closely thereto, which action lifts rod B' out of the hole in the base-plate 13 Thus rod A is released so as to be sufficiently rotated by handle A', and by means of lever C, connecting-rod D, and disk E the ends F of the transverse bars F are inserted into the holes in the skids G, (said result being accelerated bythe spiral springs F said ends F remaining therein until such time as withdrawn by reverse action of handle A', which in practice would be when the passenger has alighted from the car H. In case when a passenger is entering or about to enter a car and the conductor being duly notified he accordingly anchors the car at the desired position in sinilar manner as above referred to. It will thus be seen that during the time a passenger is either entering or leaving the car the latter is made immovable and no disagreeable feeling is experienced or danger incurred by jerkings or vibrations.-

Having now particularly described and ascertained the nature of ny said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In an apparatus for retaining an elevator car or lift at any point of its travel, the combination, with transverse rods Operating in guides secured to the under side of the floor of the car and adapted to enter holes in the skids against which the car works, of an actuating-rod mounted within the car and eX- tending through the bottom thereof, actuating mechanisn connecting the lower end of said actuating-rodwith the inner ends of said transverse rods, and a novable rod attached to the aforesaid actuating-rod within the car rotation or when elevated to pernit its rota tion, substantially as set forth.

2. The combination, with transverse rods having bent inner ends Operating in guides secured to the under side of the bottom of the elevator and adapted to enter holes in the skids against which the elevator-car works, and a disk supported centrally on the under side of the bottom of the car and having connected thereto the bent inner ends of said transverse rods, of a vertical actuating-rod mounted within the carand eXtending through the bottom thereof, a lever secured to the lower end of the said actuating-rod, and a connecting-rod jointed to the outer end of said lever and attached at its opposite end to the aforesaid disk, substantially as set forth.

3. The combination, with transverse rods having bent inner ends and Operating in guides secured to the under side of the bottom of the elevator-car, and a disk supported centrally on the under side of the bottom of the car and having connected thereto the bent inner ends of said transverse rods, of a vertical actuating-rod nounted within the car and extending through the bottom thereof, a lever secured to the lower end of said actuating-rod, a connecting-rod jointed to the outer end of said lever and having its opposite end attached to the aforesaid disk, and a locking rod or bar connected to the actuating-rod within the car and under control ot' the ele- Vator-driver, substantially as set forth.

4. The combination, with disk E, transverse rods F, having bent inner ends which are connected to said disk, and spiral springs, as F surrounding said rods F, of a vertical actuating-rod provided with a handle and nounted within the car and extending through the bottom thereof, and actuating nechanism connecting the lower end of said vertical actuating-rod to the aforesaid disk, substantially as set forth.

5. The combination, with the transverse rods, as F, adapted to enter holes in the skids against which the car works, disk E, lever C, and rod D, of the Vertical actuating-rod A, connected to lever C and having a handlc, looking-rod B', having a thumb or hand piece and connected to the actuating-rod A, a spiral spring surrounding said looking-bar, and a base-plate, as B with which the locking-rod B' cooperates, substantially as set forth.

In witn'ess whereof I have hereunto set my hand in the presence' of two witnesses.

FREDERIOK GILES.
